We have a class like this: class LogAnalyzer { protected IExtensionManager manager; publicLogAnalyzer() { GetManager();
Suppose a class Y publicly inherits a class X. Is it possible for a class Z to privately inherit Y while publicly inheriting X?
I am new to C++. While trying sample polymorphism code, I found that base class virtual function definition in derived class is possible only when defined within the derived class or outside with decl
I know that polymorphism can add a noticeable overhead. Calling a virtual function is slower than calling a non-virtual one. (All my experience is about GCC, but I think/heard that this is true for an
In hope to simplify a homework problem dealing with inheritance, I thought it might be better to use polymorphism to accomplish the task.It isn\'t required, but makes much more sense if possible.I am,
class A{ public: virtual char &operator[](int); protected: .. }; class B:A{ public: A* &operator[](int);
I\'ve been looking at DynObj and decided to do my own experimentation with vftables.I\'m working with Visual Studio 2010 and created a console main that instantiates an object with a virtual functi开发
I have a class whose objects are used in shared memory. Therefore, I must be sure that they do not have virtual methods (which crash the progr开发者_Python百科am when called via vtable).
Consider the following code (it\'s a little long, but hopefully you can follow): class A { } class B :开发者_JAVA百科 A
Just starting to use Java. I find a lot of similarities with .NET, but I see that all methods in Java are virtual by default.
